FDA Cuts Sotrovimab EUA Regions
FDA says that sotrovimab is not authorized in HHS regions 5, 9, and 10 as of 3/30 because the Centers for Disease Control and Prevention says that the proportion of Covid-19 cases caused by the omicron BA.2 variant is above 50% in those regions. An agency statement says that under terms of the emergency use authorization, sotrovimab is authorized to treat mild-to-moderate Covid-19 in adults and certain pediatric patients with positive results of direct SARS-CoV-2 viral testing and who are at high risk for progression to severe Covid-19, including hospitalization or death.
The authorization was updated 2/23 to clarify that sotrovimab is not authorized for treating mild-to-moderate Covid-19 in geographic regions where the infection is likely to have been caused by a variant that is not susceptible to the treatment. HHS regions 1 and 2 were taken off the authorized list as of 3/25.
The therapy remains authorized in the remaining HHS regions where the CDC estimates that the proportion of the omicron BA.2 variant remains below 50%. FDA says it will continue to monitor BA.2 in all regions and may revise the authorization further to ensure that Covid-19 patients have effective treatments available.
